1、MFC 程序最小化到系统托盘区的一个简单实例----http://blog.csdn.net/jarvischu/article/details/5781294

2、如何建立 WinCE 上的系统托盘图标 [转自 MSDN]----http://blog.sina.com.cn/s/blog_546badf1010008a2.html

3、如何关闭时隐藏程序而不退出？点拖盘图标后再显示出来----http://bbs.csdn.net/topics/210068798

程序在以下平台测试通过：

操作系统：Wince6.0

软件平台：EVC4.0

硬件平台：深圳友坚恒天科技有限公司ARM11开发板UT-S3C6410

在XP下我们能经常看到系统托盘的图标，也就是右下角的小图标，比如：QQ图标、音量控制图标等，那么Wince下的如何实现系统托盘呢？本文通过图解＋代码的方式详细介绍系统托盘程序实现的整个步骤。

先来看看程序实现后的效果图：

1、开机自动运行系统托盘程序

2、左键单击图标（小喇叭），上下拖动调整音量大小

3、点击“Mute“静音

4、双击打开系统音量控制界面

步骤：

1、 EVC下建立一个WCE Application Project

点击ok

2、选择A Sample Windows CE Application

点击“Finish”

3、创建并编辑对话框资源

4、插入两个托盘ICON

一个是正常状态，一个是静音状态

程序很简单，主要包括几个方面：

1、自定义一个消息用来处理系统托盘的操作

2、初始化NOTIFYICONDATA结构

3、调用API函数Shell_NotifyIcon

4、系统托盘消息处理

5、将编译生成的SoundSystemTray.exe拷贝至Wince 工程目录下

6、将在SoundSystemTray.exe 加到NK中

platform.bib中添加

SoundSystemTray.exe $(_FLATRELEASEDIR)\SoundSystemTray.exe NK S

7、设置开机自动运行SoundSystemTray.exe

platform.reg中添加

[HKEY_LOCAL_MACHINE\Init]

"Launch80"="SoundSystemTray.exe"

"Depend80"=hex:1e,00
